Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with the accompanying drawings and by detailed description of the invention.
If Fig. 1 and Fig. 2 is electric food warmer and do not place the structural representation of electric food warmer under interior pot state under pot state in present embodiment is placed respectively.As depicted in figs. 1 and 2, present embodiment proposes a kind of electric food warmer with interior pot detection device, it includes controller, base 1, interior pot 2, outer pot 3, it is positioned at outer pot 3 inner bottom part, telescopic temperature sensor 6, and signal trigger and the signal generator that is connected with controller, bottom in outer pot 3 is additionally provided with the heat-generating disc 7 for heating interior pot 2, signal trigger is connected with temperature sensor 6 and moves up and down under the drive of temperature sensor 6, signal trigger is by the opening and closing of the change control signal generator of its position, the opening and closing signal that controller sends according to signal generator, determine whether pot 2 in placement.
In the above-mentioned electric food warmer with interior pot detection device, the signal trigger being connected with the scalable temperature sensor opening and closing by its change in location control signal generator, the opening and closing signal that controller sends according to signal generator, determine whether pot in placement, the detection of pot in realizing, thus it is prevented effectively from the dry combustion method of electric food warmer in the case of without interior pot, prevent the premature aging of parts, extend the service life of electric food warmer, improve safe handling property.
In the present embodiment, signal trigger is preferably dark slide 5.Signal generator is preferably photoswitch 4, and photoswitch 4 carries out communication with the chip of controller and is connected.Photoswitch 4 is arranged on the middle part of base 1, photoswitch 4 bottom left is provided with light emitting devices (i.e. infrared transmitting device), this infrared transmitting device is sustainable launches infrared ray to bottom right, the optical pickup apparatus (i.e. infrared receiver) on right side can sense infrared light sources always, and photoswitch 4 is closed all the time.When pot 2 in placing, shutter 5 can move down under the drive of temperature sensor 6, one end away from interior pot 2 (i.e. bottom) of shutter can be stretched in photoswitch 4, when photoswitch 4 is stretched in the bottom of dark slide 5, dark slide 5 can block the infrared ray being transmitted into infrared receiver by the infrared transmitting device of photoswitch 4, and photoswitch 4 is changed into open mode by closed mode, now, controller is judged as there is interior pot 2, and electric food warmer can enter duty.When pot 2 in not placing, dark slide 5 does not has gravity pressure-bearing, will not move down and stretch in photoswitch 4, the bottom right of photoswitch 4 can persistently sense the infrared ray that left side is launched, photoswitch 4 is not operating, all the time being closed, now controller is judged as that electric food warmer cannot be introduced into duty without interior pot 2.
This electric food warmer with interior pot detection device also includes the alarming device being connected with controller, for sending prompting when without interior pot 2.Alarming device is display reminding device or sound prompt device.As a example by display reminding device is as display panel, when being judged as without interior pot 2, photoswitch 4 feeds back this signal to controller, controller is transferred to one signal of telecommunication of display panel, display panel can show run-time error information, such as display " E1 " printed words, and prompting user places interior pot 2 in time.As a example by sound prompt device is as buzzer, when being judged as without interior pot 2, photoswitch 4 feeds back this signal to controller, and controller controls buzzer and sounds a buzzer, and points out in a voice form without interior pot.The setting of alarming device effectively prevent the dry combustion method of electric food warmer in the case of without interior pot, improves the safety of electric food warmer, extends the service life of electric food warmer.
As a kind of preferred version, above-mentioned signal generator is current loop, and signal trigger is the conducting rod controlling current loop opening and closing, and conducting rod accesses under conducting rod decline state away from one end (i.e. bottom) of interior pot and turns on current loop.Conducting rod controls being turned on or off of current loop by its change in location, and controller determines whether interior pot according to the signal that is turned on or off of current loop.
Further, conducting rod is non-conducting material close to one end (i.e. top) of interior pot, its other end (i.e. bottom) is conductive material, so, when pot in placing, the top of conducting rod contacts connection with temperature sensor, and conducting rod moves down under the drive of temperature sensor, so that current loop is accessed and connected in the bottom of conducting rod, and top employing non-conducting material avoids current loop and impacts the normal work of temperature sensor.
As another kind of preferred version, above-mentioned signal generator is LOAD CELLS, and signal trigger is drive link, and drive link contacts connection away from one end of interior pot under drive link decline state with LOAD CELLS.Drive link reaches whether to contact connection, the signal of telecommunication that controller sends according to LOAD CELLS with LOAD CELLS by its change in location, it is judged that with or without interior pot.
Signal generator and the signal trigger of the application are not limited to said structure, it is also possible to for can other versions of the various current switch of opening and closing, be drive link such as signal trigger and signal generator be the version etc. of displacement transducer.
Additionally, present embodiment also proposes the interior pot detection method of a kind of electric food warmer, it is specially, when pot 2 in placing, under the gravity pressure-bearing of interior pot 2, signal trigger declines along with temperature sensor 6 and declines, and opens signal generator simultaneously, signal generator sends to controller and opens signal, it is judged that for there being interior pot 2；On the contrary, then signal generator sends shutdown signal to controller, it is judged that for without interior pot 2.
Further, when being judged as without interior pot 2, controller sends the signal of telecommunication to display panel, makes display panel show run-time error signal.
Know-why of the present utility model is described above in association with specific embodiment.These descriptions are intended merely to explain principle of the present utility model, and can not be construed to the restriction to this utility model protection domain by any way.Based on explanation herein, those skilled in the art need not pay performing creative labour can associate other detailed description of the invention of the present utility model, within these modes fall within protection domain of the present utility model.
